A View-Dependent Stereoscopic System Using Tiled Projection

In this paper, we present a novel system which allows its users to see a stereoscopic virtual object. Unlike most existing stereoscopic systems that display the same imagery when watched from different directions, the user's head is tracked in real-time so that the real-time images can be rendered according to the viewing position, which enables the dynamic images to be displayed on the screen and the users can see different parts of a virtual object when wearing a pair of polarized glasses. This creates a more vivid illusion that a real object is set at the physical scene. The key technologies of the proposed system such as depth-image-based head tracking, geometric calibration and view-dependent real-time stereoscopic image rendering are studied and the experimental results proves the performance of the proposed system.
